9 Claims. (Cl. 221-23) This invention relates in general to an improved device for dispensing liquids. and more particularly to expeditiously dispensing a unit charge of lubricating oil from a sealed container.

The principal object of the invention is to provide the combination of a readily frangible, tamperproof, oil container adapted to'cooperate'with a simple, inexpensive, funnel spout adapted to fit over and make liquid tight locking engagement withthe frangible container, so th'at'a unit charge of oil may be readilydispensed from the container through the funnel spoutand directly into the filling opening of an automobilecrankfcase .or other "ultimate place of: deposit.

. 'An important object of the invention is provision of a novel method of dispensin the g branded or labeledm'otor oilsin sealed, tamperproof containers in an expeditious and economical manner, which method is designed to substantially prevent-substitution and .adulteration of the 'oils and to protect the ultimate consumer against adulterated and inferior quality.

'Another important object of the invention is the provision of such an oil container having locking projections upon a part thereof which cooperate with like projections upon pensing device, sothat-both container the disand. de-

vice may be readily brought into intimate and liquid tight locking engagement forthe dispensation of the contents.

Another important. object of the inventionis the provision of 'acombination' pouringspout and funnel, shaped and dimensioned so as to conduct and transfer liquids, suchxas lubricating oils, from a substantially widely opened container to aflmbre orles's restricted opening. in

the ultimate place of deposit, such as the filling holes of automobile crank cases, which size and accessibility according to differ in different makes and sizes of cars, and to make such' transfer;speedily and with a minimum' was te of oil and motion. and witha minimum soiling oflthe devices involved. 7

Still another important object of thei is the provision of such a combination nvention pouring spout and delivery funnel of simple and inexpensive construction, provided with a sealing gasket and cooperating iwitha readily frangible container of metal or fibre or partly metal and partly fibre, for dispensinga unit charge of oil from such containers, the whilesealingly interlocking with said container and without resort to the expensive equipment nowin use stations and elsewhere. i

'Numerous other objects and advantag at filling es of the of Fig. 2.

invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses V a preferred embodiment thereof.

Referring to the drawing:

Figure lris a perspective view of a suitable oil container with scored top end and illustrates the removal of the scored end;

Fig. 2 is a perspective View of the container and funnel spout, with parts broken away, in interlocked or threaded relationship;

Fig. 3 is a .partly sectional, partly elevational view, showing the interlocked or threaded container and funnel spout in tilted or pouring position; l M

Fig. 4 is a fragmentary, ,horizontalsectional View taken along the lines 4-4 of Fig.2;

Fig.5 is a fragmentary, vertical sectional view takenalong the lines 5-5 of Fig. 2; and

Fig; 6 is. a like view taken along the lines 66 V The preferred embodiment ofthe invention illustrated in the'drawing, comprises generally a sheet metal containerA and a substantially bottle shaped funnel and pouring spout B, also made of sheet metal of somewhat heavier gauge than the metal of the container.

Preferably, the container A illustrates a size to hold an exact unit charge of lubricating oil,

for example, a quart. It may, however, be made me number of different sizes, for instance, half gallon, gallon or five quart size, or any other desired size. It comprises a cylindrical body 11,

having a bottom end secured to it by means of a 3 double seam 12, or in any-suitable liquid tight manner. A top end is secured to the opposite end of the body 11 by a like seam 13, and has a countersunk flat panel 14 provided with an annular score line 15, located just within the upwardly projecting seam 13. The container is opened by breaking through the score line 15 with a sharp instrument such as a pocket knife. or a screw driver 16 and prying up the panel 14 either partly,

as shown in Fig; 1, or entirely removing the panel.

The funnel spout B, preferably made from seamless brass or copper tubing, and gradually reduced by spinning from its largest diameter to its smallest diameter is substantially bottle r shaped.

It comprises a tubular body 1'7 of comparatively large diameter at its lower end and at its upper end gradually tapering into a comparatively small diameter tapered neck or spout 18, which, at itsouter extremity, defines a restricted circuspaced intervals around its periphery, with in-' wardly projecting locking threads 24 and companion stop lugs 25. Each locking thread 24 is formed by cutting the metal of the flange 23 vertically along parallel, spaced lines and along a line inclined from the horizontal and connecting the vertical cuts, leaving the bottom connected with the flange and bending inwardly the cut metal.

Each stop lug 25 is formed by indenting the metal of the flange 23 alonga line substantially horizontal with the highest point of the slanting o-r inclined cut end slightly spaced away from the thread 24. Three sets of locking threads and companion stop lugs are preferably employed.

To cooperate with these locking and stop elements on the funnel spout B, corresponding looking projections are provided on the container A by squeezing and projecting outwardly the metal of the top seam 131at three spaced points 26 about theperiphery of the seam 13. These looking projections or threads 26 may be produced by a suitable die or squeezer jaw operation after the double seam 13 is formed in the usual manner and without endangering the tightness of the seam 13. v I

.It will be readily seen that instead of spinning the funnel spout B from seamless tubing,it may well be formed from a fiat blank of any suitable sheet metal, in which case the edges of the blank would be joined in a side seam.

Also, the shoulder 21 and collar 23 may be joined to thebody 17 as a separate piece instead of being integral with the body as is shown in the preferred illustration.

In order to assure the ultimate'purchaser that he gets the brand and quality of lubricating oil he asks and pays for, the tamperproof oil container A may be marked with the brand of oil' it contains, by lithographing or labeling or in any other suitable manner. Fig. 1 shows one example of such marking.

The funnel spout B may be made in a number of different sizes and diameters to threadedly fit the corresponding sizes and diameters of oil containers above referred to. r

In actual dispensing practice, the oil container A and the funnel spout dispenser B may be manipulated as follows: a

When a unit charge of oil of a certain requested brand is to be dispensed into the crank case of an automobile at a filling station, the attendant selects a filled, sealed and labeledoil container A of the desired size and brand and opens it (preferably in full view of the purchaser) by prying up the panel 14 along the score line 15 by; means of any handy, sharp instrument or tool, such as a screw driver or knife, so that a substantial pouring opening is provided (see Fig. 1). If preferred, the entire panel 14. may be thus removed.

The attendant then selects the proper size funnel spout dispenser B and inverts the wide, open end of the spout over the top of the opened container A, with the three sets of threads 24 and lugs 25 located between the seam projections or threads 26 of the container, until the top edge of the seam 13 engages the gasket or packing 20 in the shoulder recess 22. 'He thenrotates' the funnel B upon the container A in a clockwise direction, when the inclined thread 24 catches under the nearest seam projection 26-and slides upon it until. the latter engages. the. stop lug 25. By this time, the somewhat resilient gasket 24 has been tightly drawn down against the seam 13 and forms with the latter a liquid tight seal which eifectively prevents the escape of any oil between, V

such seal. 7

' The container and funnel are then tilted to pouring position, as illustrated in Fig. 3, where reference letter C denotes the filling neck of an automobile crank case. The oil isthus readily transferred from the container A, through the funnel B, and into the filling opening of theorem case. I

.. Instead of merely resting the part 18 upon the part C, the funnel neck 18. may be projected into the filling opening ofthe crank case a sufllcient distance to hold'the funnel B and attached: cone tainer A in fully inverted, substantially vertical pouring position without other support. The at tendant may then'leave thedevice in thisposition while he goes for another container and funnel. In order to permit the rapid draining ofthe oil, an air vent hole'27 is provided inthesbody 1.7

of the funnel spout The funnel neck 18 is of such diameter-"end taper that it will readily fit the. filling-hole of any standard motor car from the largest make. r U

It is thought that the invention and manyot its attendant advantages will be understood from the foregoing description, and it will! apparent that various changes maybe made in the construction and arrangement of the parts with' smallest to the out departing from the spirit and scope of the 2.
